Eccentric shaft motor? On E92.

My car had problem with Eccentric Shaft sensor. They had replaced it and the problem atarted on the next day. The car stalled while driving.

The car has been in dealer for 2 weeks now.

They called me today and they might replace the Eccentric Shaft. (Im guessing motor).

Is this.... big problem?? Anyone know??

The Valvetronic motor connects into the eccentric shaft which is connected to the valvetrain under the cylinder head cover. It isn't a huge job with the right tools.

Should it fix the problem?
It is funny because my dealer told me that they will have to call somewhere to see if they let me get the shaft replaced.

The problem was after replacing eccentric shaft sensor. The car stalls while driving.

Special tools, or do you mean a well equipped mech?

Replace the shaft - isn't that extreme?

The car has service engine soon light.
The car stalls sometimes.

The error code they get is related to the eccentric shaft..

The seal around the eccentric shaft sensor can deteriorate causing engine oil to get into the connector above the sensor. Hesitation in acceleration can occur.
The engine cover must be removed to see it. This is common on the N52 motor.

Look at this.

I just got back from dealer. They had order the Eccentric Shaft. And will be replaced tomorrow.
The engine cover and all the other stuffs were taken off but they couldn't find ANY problem. So they decide to replace the Shaft first and see.

I hope it fixs everything///

Okay, I admit I did read your entire post, but I completely disregarded the second sentence. They already replaced the sensor (duh) now it's time to replace the actual motor. Okay. Gotcha.

Eccentric shaft motor? On E92.

I've seen this fault caused by engine oil getting pushed through the engine harness connector via the eccentric shaft sensor. In some cases, the oil makes it way all the way to the DME. At that point, the sensor, engine harness and DME all need to be replaced.
